Resident Evil 6 Wiki Guide

Characters

Returning lead characters are Leon Kennedy (Resident Evil 4) and Chris Redfield (Resident Evil 5). Leon and Chris have new characters as partners: Helena Harper and Piers Nivans, respectively. The third pair of playable characters are Sherry Birkin (Resident Evil 2) and new character, Jake Muller. Ada Wong is also a playable character who can be joined by the mysterious character only known as Agent during her section of the campaign.

Ada Wong's campaign is the fourth perspective on the Resident Evil 6 story. Originally, Ada's storyline became available to players after the Chris, Leon and Jake arcs had been completed (probably similar to the 'Assignment Ada' bonus mission in Resident Evil 4). As of December 17th, Ada's campaign can be played at any time, due to a title update.[1] All main story branches are now selectable from the beginning of the game, allowing players to see each storyline through to completion before starting another one. It also allows players to play chapters from each campaign in the order they choose. Before the update, Ada's section was single player only, although now Ada can be joined by the Agent (although he has no discernable effect on the story other than allowing her campaign to be played cooperatively).
